Use Extreme Tuning in GarageBand for iOS

Using Extreme Tuning, you can apply a popular vocal pitch correction effect to your vocal tracks on your iPhone, iPad, or iPod touch.

When using Extreme Tuning, set the key of your song in GarageBand before applying the effect for best results. You can then additional effects like echo or reverb.

Set the key and scale of the song

Extreme Tuning uses your song's key and scale settings to apply the effect. If the actual key or scale of your song differs from the key or scale setting, the effect might be less pronounced, or might change the pitch of individual notes in the track in undesirable ways.

GarageBand songs defaults to the key of C.

On iPhone and iPod Touch, tap Settings in the control bar, and then tap Song. On iPad, iPhone 6 Plus, and iPhone 7 Plus, tap Song Settings in the control bar.

Tap Key.

Tap the key for your song.

Tap the scale for your song (major or minor).

Access the Extreme Tuning setting

Extreme Tuning is optimized for male and female voices, but you can apply it as a creative effect to any mono audio track, like a bass guitar or other live instrument.
